Baylis on tome is surrounded by papillae, of which two are lateral (fig. 5, ) and four subniedian (fig. 5, ), the latter being apparently double papillae. The terminations of the papillae are at the bases of small funnel-like cuticular depressions. The oeso- phagus is simple, increasing slightly in diameter posteriorly, and both it and the anterior part of the intestine are very slender. The length of the oesophagus "is 1*2 mm. in the male and 1*3

Baylis on tome is surrounded by papillae, of which two are lateral (fig. 5, ) and four subniedian (fig. 5, ), the latter being apparently double papillae. The terminations of the papillae are at the bases of small funnel-like cuticular depressions. The oeso- phagus is simple, increasing slightly in diameter posteriorly, and both it and the anterior part of the intestine are very slender. The length of the oesophagus "is 1*2 mm. in the male and 1*3 mm. in the female. There is a pair of: very prominent lateral neck-papillse situated at about half the length Fig. Thelazia depressa. Tail of female ; ventral view. caudal papilla. of the oesophagus from the anterior end. The nerve-ring surrounds the oesophagus at 0*5 mm. from the head-end. No excretory pore has been detected. The tail, in both sexes, ends bluntly in a slight knob-like swelling, which is most pronounced in the female. The caudal end of the male (tig. 6) is curved towards the ventral side, and the tail itself measures 0*3 mm. in length. There are no caudal alae. Tire caudal papillae are small ; there are about fifteen pairs—four postanal (close together), one pair.
